C.4 · Duration, latency and interresponse time
Grab your stopwatch, because today it's all about time! Duration, latency, and interresponse time all measure time, and they're easy to mix up until you know one simple question to ask.
Key takeaway
Duration is how long a response lasts, from its onset to its offset. Latency is the time from the onset of a stimulus, such as an instruction, to the start of the response. Interresponse time, or IRT, is the time between two consecutive responses of the same class. To tell them apart, ask what starts the clock and what stops it.
